I have used the VIP Select service twice both times in ATL.

One one was connecting to an INTL flight in ATL that service was great with the porsche picking you up when your first flight lands. They sneak you in the back of the lounge and then drive you to the next plane when it is ready to go.

The second time I was also connecting in ATL landing as an intl passenger I would say the service was not as helpful in this situation as oyu have to walk all the way to customs and go through regular immigration/get your bags and re drop them to your connecting flight.

I will be using VIP select on an upcoming flight departing LAX on the way to JFK
